Orealla (or Orealla Mission) is an Native Indian community in the East Berbice-Corentyne Region of Guyana, on the Courantyne River, approximately 33 miles (53 km) south of Crabwood Creek and 11 miles (18 km) north of Epira, located at , altitude 11 metres. 15 miles (24 km) south-east on the other side of the Courantyne River lies the Surinamese village of Apoera.
Orealla is the only American Indian community that has had the boundaries of its reservation demarcated, with a total area of 266 sq mi (690 km2).
The recent involvement of Orealla with the Barama Company, Limited, demonstrates a major weakness of the reservation system, which while providing a large degree of autonomy to Amerindian communities may also cut them off somewhat from central sources of advice and assistance, exposing them to such predatory incursions from outside parties.
Small ocean-going vessels are able to navigate the Courantyne River for about 70 km, to the first rapids at Orealla.
